High-position air inlet pipe assembly with axial swirling pipe

Abstract

The invention discloses a high-position air inlet pipe assembly with an axial swirling pipe. The high-position air inlet pipe assembly comprises an upper shell, a lower shell, a first partition plate,a second partition plate, the axial swirling pipe and a dust discharge valve, the upper shell and the lower shell are welded together, a cavity is formed inside the upper shell and the lower shell, the first partition plate and the second partition plate are sequentially arranged in the cavity from left to right, and the first partition and the second partition are used for sequentially dividingthe cavity from left to right into a dust discharge cavity, an air inlet cavity and an air outlet cavity. Due to the adoption of the technical scheme, the high-position air inlet pipe assembly has thebeneficial effects that the advantages of being low in original resistance and high in pre-filtration efficiency are achieved; the original resistance is reduced, the oil combustion rate and the oilconsumption of an engine are improved, the emission of pollutants is reduced, and the high-position air inlet pipe assembly has an important significance for environmental protection; the pre-filtration efficiency of an air inlet pipeline is improved, the utilization rate of the filter element of an air filter is improved, the wood pulp fiber consumed by the filter element is reduced, the using amount of the wood is reduced, and the high-position air inlet pipe assembly has the important significance for the environmental protection.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a high-position intake pipe assembly with an axial swirl pipe. Background technique [0002] Medium and heavy trucks are mainly used in road transportation and construction machinery. They are often used to transport soil, stones, gravel, coal, ore, grain and other materials. Due to the nature of the work, the working environment of medium and heavy trucks has a large dust concentration and long working hours. , This working state requires the air intake system to have high filtration efficiency and service life, thereby reducing the maintenance cost and frequency of maintenance for consumers. The car air intake system plays a key role in protecting the engine. The original filtration efficiency of the intake system, the original resistance of the intake air, the coarse filtration efficiency, and the life of the laboratory are directly related to the running-in and fuel consumption of t...

AI Technical Summary

Problems solved by technology

[0003] There are two main problems in the air intake system of medium and heavy trucks on the market: on the one hand, the original resistance of the air intake system is relatively high, which leads to insufficient air intake of the engine and increases the fuel consumption of the engine

At the same time, the original resistance of the air intake system is high, resulting in low dust holding capacity of the air filter element, and the filter element will be frequently maintained and replaced, increasing the maintenance cost of consumers

On the other hand, the pre-filtration efficiency of the air intake system is low, and the dust concentration in the working environment of medium and heavy trucks is high. The dust entering the air intake system is relatively large, and the pre-filtration efficiency is low. The dust entering the air intake system cannot be discharged from the air filter in time and enters the filter element. Internal, resulting in frequent filter maintenance and filter replacement, resulting in increased maintenance costs for consumers

[0004] At present, the air intake system of medium and heavy trucks is mainly divided into three structures. One is to install a straight-through swirl pipe for the high air intake pipe. This structure of air intake system is not widely used on medium and heavy trucks. The main problems are: The high-level pipe with this structure has a low coarse filtration efficiency, and the coarse filtration efficiency only reaches about 40%. If it is installed on the whole vehicle, the maintenance frequency of the air filter and the replacement frequency of the filter element will be increased.

The other two are the oil bath air intake system and the desert swirl tube air intake system. The oil bath air intake system often loses oil, and the filter element is not easy to maintain

The desert swirl tube air intake system is determined by the air intake method, and the air intake system has high resistance, so relatively speaking, it consumes a lot of fuel
